DEMONSTRATION CAPABILITIES

PCT20H HARDWARE

Proportional output for PID control (proportional, integral and derivative actions) of a measured process variable.

Volt free relay output for time proportioned or on/off control.

Universal inputs:

> 4 to 20mA

> 0 to 5V

> 1 to 5V Type

> k Thermocouple

Engineering units can be configured to suit each application e.g. degrees C or F, ml/min or gal/min.

Alarm output (N/O and N/C volt free contacts) for limit control demonstrations from analogue input.

Remote set-point operation.

Adaptive tune i.e. optimisation of PID settings.

RS485 serial communications, for connection to industry standard networks. (RS485 not required for Armfield demonstrations).

RS232 to RS485 converter for connection to standard PC serial port (RS485 interface card not required in PC).

Dual set points for customer applications where two sets of PID parameters may be required.

Alternative control algorithm to minimise overshoot.

PCT20H SOFTWARE

Software is supplied to demonstrate serial communications with the controller and introduce SCADA. A number of pre-set configurations are included that can reset the controller to suit specific applications.

The computer program supplied with PCT20H uses the familiar Windows style toolbars that include the following functions:

View/PID allows PC supervision of the PID controller. The user can read or write the following controller parameters: Set-point, Proportional Band, PID parameters, Alarm value, Direct/reverse action, manual/automatic output, polling interval (logging).

View/Messages allows the user to input formatted messages for extensive interrogation and setting of the UDC3300.

View/Configuration allows the user to read the current settings in the UDC3300 and write settings to the controller. The Recall menu can be used to load various pre-set configurations for Armfield products such as PCT23MkII, which can then be uploaded to the UDC3300.

View/Table presents a table of parameters that have been logged when the auto-polling feature has been turned on and logging enabled.

Comms/Read allows the existing configuration of the controller to be read into the configuration screen for analysis.

Comms/Write allows all settings on the configuration screen to be uploaded to the controller.

SERIAL COMMUNICATIONS

RS232 to serial port of PC (not supplied by Armfield) RS485 to other controllers (Armfield software not supplied)

ESSENTIAL ACCESSORIES

- PC with one RS232 serial port

- The PID controller requires an appropriate item of Armfield Process equipment in order to supply power to the unit.

The relevant Armfield items are:

> Process Plant Trainer, PCT23MkII

> Distillation Columns, UOP3BM or UOP3CC

> Basic Process Control System PCT40 with Electronic Console PCT43

(see relevant literature for above items)
